Externalizing configuration file

[EchedelleLR]

To avoid the issue with recurrent update in the internal model, which may overwrite or force overwriting configurations or issues to update because is a Git tracked file with source code, I thought about the use of an environment or even JSON config file that is untracked by Git (gitignore) but shows an example file like .env.sample or config.json.sample.

I have no idea or Ruby to make it properly but maybe there is a gem such as Python DotEnv library to make it easier with environment files.
